tfa promoted direct c h Sulfenylation at the c2 position of non protected indoles
ChemInform, 2016Co-Authors: Thomas Hostier, Vincent Ferey, Gino Ricci, Domingo Gomez Pardo, Janine CossyAbstract:The practical and efficient metal-free Sulfenylation is performed on variously substituted N-protected and N-unprotected indoles using N-arylsulfanyl, N-hetarylsulfanyl or N-alkylsulfanylsuccinimides.

tfa promoted direct c h Sulfenylation at the c2 position of non protected indoles
Chemical Communications, 2015Co-Authors: Thomas Hostier, Vincent Ferey, Gino Ricci, Domingo Gomez Pardo, Janine CossyAbstract:A simple, efficient and practical metal-free C–H Sulfenylation process at the C2 position of non-protected indoles has been developed. 2-Thioindoles were obtained in moderate to high yields using stable and readily available N-(thio)succinimides at room temperature in the presence of TFA.

synthesis of aryl sulfides metal free c h Sulfenylation of electron rich arenes
Organic Letters, 2015Co-Authors: Thomas Hostier, Vincent Ferey, Gino Ricci, Domingo Gomez Pardo, Janine CossyAbstract:A simple, efficient, and practical metal-free C–H Sulfenylation of substituted electron-rich arenes has been developed. This method is highly regioselective, and the corresponding aryl sulfides were obtained in moderate to excellent yields from stable and readily accessible N-(alkylthio)- and N-(arylthio)succinimides at room temperature in the presence of TFA.

accounting for different reactivities of sulfinate and thiosulfate salts in regioselective azetidine coupling via c h Sulfenylation of indoles
Synlett, 2017Co-Authors: Muhannad A E Alsaedy, Annechloe M A Nassoy, Joseph P A HarrityAbstract:The regioselective incorporation of azetidines into heteroaromatic compounds is reported via a formal C–H Sulfenylation reaction. While sodium sulfinate salts undergo C3 Sulfenylation of electron-rich indoles only, the corresponding thiosulfate salts have proved to be more generally useful. A mechanistic hypothesis for the different reactivities of sulfinate and thiosulfate salts is provided.

dual role of p tosylchloride copper catalyzed Sulfenylation and metal free methylthiolation of imidazo 1 2 a pyridines
ChemInform, 2016Co-Authors: Chitrakar Ravi, Darapaneni Chandra Mohan, Subbarayappa AdimurthyAbstract:Copper-catalyzed regioselective C-3 Sulfenylation of imidazo[1,2-a]pyridines using p-tosylchloride as a benign source of sulfenylating agents has been developed. On the other hand, p-tosylchloride mediated thiomethylation of imidazo[1,2-a]pyridines with dimethylsulfoxide as a source of thiomethylation under metal-free conditions was also described.

dabco agoac cooperatively catalyzed α Sulfenylation of isocyanoacetates with n sulfanyl succinimides
Tetrahedron Letters, 2019Co-Authors: Meixin Zhao, Qiang Liu, Ronghui Jiang, Min ShiAbstract:Abstract The first organo/metal cooperatively catalyzed α-Sulfenylation of isocyanoacetates with N-(sulfanyl)succinimides has been developed. The reaction condition was suitable to α-aryl and alkyl-substituted isocyanoactates as well as N-(arylthio)succinimides, affording the corresponding products with high yields (90–96%). Preliminary asymmetric organocatalysis has also been evaluated.
